The invention provides a closed air supply unit system for an air suspension and a control method of the closed air supply unit system, aims to improve the air supply efficiency of an air suspension system, reduce energy consumption and noise and ensure the drying quality of compressed air, and comprises a reversing valve PV1, a pre-control valve SV1, an electromagnetic valve, a pressure sensor PS, a one-way valve, a dryer AD and a compressor C. The reversing valve PV1 is responsible for controlling the flow direction of compressed air, the pre-control valve SV1 controls state switching of the reversing valve, the electromagnetic valves SV2 to SV5 manage inflation and exhaust of an air spring, the pressure sensor PS monitors the pressure of the system, the one-way valve ensures one-way flowing of airflow, the dryer AD dries the compressed air, and the electromagnetic valve SV8 controls back blowing and gas emptying of the dryer. The system achieves efficient gas supply and energy conservation through accurate control and monitoring, meanwhile, vibration and noise are reduced, and the stability and reliability of the system are improved. In addition, the design of the system also considers the simplicity and convenience of maintenance and operation, so that the overall performance is improved and the service life is prolonged.
